Optimism and Arbitrum flip Ethereum in combined transaction volume By Cointelegraph

layer-2 on-chain activity has been increasing to the extent that the leading two networks now process more transaction volume than mainnet Ethereum.

Layer-2 networks Arbitrum and Optimism have seen an increase in transactions over the past three months. Comparatively, aside from a few spikes, transactions on the Ethereum network have declined by around 33% since late October, according to Etherscan.
